Irving Street west of the busy 19th Avenue thoroughfare in San Francisco has been dense with produce markets, restaurants and snack shops for more than two decades. A fun, eclectic stop for shoppers and diners alike, it’s still ground zero for the fickle world of Asian snacking, with an ever-changing array of fresh-faced storefronts testing out the next big bite.

1. Heartland SF: A thoughtful and highly unusual collection of packaged and frozen organic foods from Taiwan to the Golden State are sold at this serene shop run by the Buddhist Heartland Society of Northern California. Stock up on healthy staples like flax seeds while experimenting with turmeric dumplings, miso cheese and Chinese pancakes with cedar shoots. 2245 Irving St., S.F.; (415) 753-3544.

3. Aruba: Taiwanese street food and bento boxes are served out of this sliver of a space that seems to constantly turn over into a new concept. The focus here, unique to the neighborhood, is on broth-marinated combinations of items like pork intestine, chicken gizzard, enoki mushroom and five-spice tofu. 2146 Irving St., S.F.; (415) 988-5525.

4. Que Huong Vietnamese Deli: A longtime area staple for banh mi sandwiches, Que Huong moved into a larger space with room for an eat-in counter in 2013, which brought a broader menu of quick-serve meat and noodle dishes. It’s also one of the area’s only purveyors of fresh-pressed sugarcane juice. 2138 Irving St., S.F.; (415) 682-3828.

5. Swich: Customizable ice cream sandwiches from mom and pop owners have been a cool replacement for a corporate frozen yogurt shop. House-baked square cookies in fun flavors like ginger and red velvet and toppings for the sides distinguish it from the pack. Swich recently ventured into hot pressed sandwiches in varieties like Seoul roast beef and herb-rubbed chicken. 2045 Irving St., S.F.; (415) 592-8091.

6. Tpumps: While Wonderful Foods down the street was the first to serve tapioca drinks (now more widely known as boba tea), the new neighborhood champion is Tpumps, as evidenced by the daily lines out the door. It’s got honey-soaked boba and several format choices, including smoothies and slushies, but doesn’t have Wonderful’s old-school Asian flavors like durian and taro. 1916 Irving St., S.F.; (415) 702-9244. http://tpumps.com
